My home wireless routing power supply specification is nine volts, zero Luan, what is the power?

150 can't buy a route with far signal transmission, and 150 of D-LINK can cover 25 meters and cross two walls, which is enough. If you need wider signal coverage, then choose Cisco's 400, covering 100 meters.

Supplement:

By the way, my data was tested by myself. Theoretically, it will go further than what I said, but in fact it can't be achieved.
